C Program Only

Retrieving a GIS Record Located at a Given File Offset

You will implement the following function in C, and place the implementation in a file named recordRetriever.c:

Returns the GIS record at the given offset.

Pre: gisFile is open on a GIS record file

offset is a valid offset for the given GIS record file

Returns: a valid C-string holding the specified GIS record

char* retrieveRecord(FILE* gisFile, uint32_t offset);

Assumptions you may make in designing your solution:

The GIS record file will correspond exactly to the description given earlier, but it will be a different file than the one shown earlier in this specification.

No line in the GIS record file will be longer than 500 characters, including the line terminator.

The caller will ensure that all the stated preconditions are true.

Use int fseek(FILE* stream, long offset, int whence) and void* calloc(size_t nelem, size_t elsize); to implement this function.
